2025-03-10Expand and organize `offset_of!` documentation.Kevin Reid-21/+41
* Give example of how to get the offset of an unsized tail field (prompted by discussion <https://github.com/rust-lang/rust/pull/133055#discussion_r1986422206>). * Specify the return type. * Add section headings. * Reduce “Visibility is respected…”, to a single sentence.

2025-03-10Mark some std tests as requiring `panic = "unwind"`Paul Menage-2/+39
This allows these test modules to pass on builds/targets without unwinding support, where `panic = "abort"` - the ignored tests are for functionality that's not supported on those targets.

2025-03-10Disable CFI for weakly linked syscallsBastian Kersting-0/+27
Currently, when enabling CFI via -Zsanitizer=cfi and executing e.g. std::sys::random::getrandom, we can observe a CFI violation. This is the case for all consumers of the std::sys::pal::weak::weak macro, as it is defining weak functions which don't show up in LLVM IR metadata. CFI fails for all these functions. Similar to other such cases in https://github.com/rust-lang/rust/issues/115199, this change stops emitting the CFI typecheck for consumers of the macro via the \#[no_sanitize(cfi)] attribute.

2025-03-10Implement default methods for io::Empty and io::SinkThalia Archibald-11/+216
Eliminate any redundant, unobservable logic from the their default method implementations. The observable changes are that `Write::write_fmt` for both types now ignores the formatting arguments, so a user fmt impl which has side effects is not invoked, and `Write::write_all_vectored` for both types does not advance the borrowed buffers. Neither behavior is guaranteed by the docs and the latter is documented as unspecified. `Empty` is not marked as vectored, so that `Chain<Empty, _>` and `Chain<_, Empty>` are not forced to be vectored.
2025-03-10Rollup merge of #138074 - thaliaarchi:hermit-seek, r=ChrisDentonMatthias Krüger-8/+25
Support `File::seek` for Hermit `lseek` was added in `hermit-abi` in commit [87dd201](https://github.com/hermit-os/hermit-rs/commit/87dd201a14ac7661e1a4b761273e24d750496286) (add missing interface for lseek, 2024-07-15), which was just released in version 0.5.0. cc ``@mkroening,`` ``@stlankes`` Fixes https://github.com/hermit-os/hermit-rs/issues/652

2025-03-10uefi: fs: Partially implement FileAttrAyush Singh-15/+11
- Just the permission and file type. - FileTimes will need some new conversion functions and thus will come with a future PR. Trying to keep things simple here. Signed-off-by: Ayush Singh <ayush@beagleboard.org>
2025-03-10uefi: fs: Implement FileTypeAyush Singh-30/+10
- Similar to FilePermissions, using bool to represent the bitfield. - FileType cannot be changed, so no need to worry about converting back to attribute. Signed-off-by: Ayush Singh <ayush@beagleboard.org>
2025-03-10uefi: fs: Implement FilePermissionAyush Singh-21/+16
- UEFI file permissions are indicated using a u64 bitfield used for readonly/filetype, etc. - Using normal bool with to and from attribute conversions to FilePermission from overriding some other bitfields. Signed-off-by: Ayush Singh <ayush@beagleboard.org>
2025-03-09std: move stdio to `sys`joboet-150/+77
As per #117276, this moves the platform definitions of `Stdout` and friends into `sys`. This PR also unifies the UNIX and Hermit implementations and moves the `__rust_print_err` function needed by libunwind on SGX into the dedicated module for such helper functions.

2025-03-09Rollup merge of #138233 - smmalis37:no-advapi32, r=ChrisDentonMatthias Krüger-1/+1
Windows: Don't link std (and run-make) against advapi32, except on win7 Std no longer depends on any functionality provided by advapi32, so we can remove it from the list of external libraries we link against. Except, the win7 targets do still rely on advapi32-provided functionality. This PR therefore moves linking against it to only occur on win7 targets, so that no new uses of it slip in without being noticed.
2025-03-09Rollup merge of #138228 - TDecking:master, r=jhprattMatthias Krüger-3/+8
Use `disjoint_bitor` inside `borrowing_sub` This makes the definition of `borrowing_sub` consistent with that of `carrying_add`.
